• When I visit a site, firefox reports invalid security certificate, but does not add an exception

  When I visit a site that has an invalid security certificate, my mobile me has a nice little dialog box telling me that the connection is not reliable and allowing me to view the site by clicking on ""I understand the risks"my office however shows a completely different dialog box." It is a simple dialog with a title of "Alert" and said... use a security not valid certificate... I don't trust blah blah and an ok box so I can never continue on the site.

• Firefox pr5esents false (false) sites when searching for my Bank and scurity said these sites (which seem to be authentic) have no security certificate

  When I search my bank using www.lloydsbank.com a page that looks authentic, but when you try to access account details access is denied because the site is not the necessary security certificate. Then he said: the site, that I asked has been online.lloydsbank.com which is obviously false. I managed to access the correct site continuously through a different browser.

  Check the date and time of the clock on your computer: (double) click on the clock icon in the Windows taskbar.

  Try renaming the file cert8.db in the Firefox profile folder in cert8.db.old or remove the cert8.db file to remove the intermediate certificates that Firefox has stored.
  
  
  If it helped to solve the problem, then you can delete the renamed file cert8.db.old.
  
  Otherwise you can rename (or copy) the file cert8.db.old to cert8.db to restore previous intermediary certificates.
  
  Firefox automatically records the intermediate certificates when you visit Web sites that send such a certificate.

  If that didn't help then remove or rename secmod.db (secmod.db.old) as well.

• invalid security certificate

  When I connect to a site with a self-signed certificate, sometimes I get: "{site} uses an invalid security certificate." I can add an exception for self-signed certificates, but what does it mean when the security certificate is not valid.

  Some sites are just security certificates that have expired. So if you connect to this website, it will tell you that its a "security certificate not valid." It simply means that the owner of the site must renew its certificate.

• I need to create public and private keys for the security certificate and I can not find the certificate. Where is he?

  I bought a security certificate, and the site tells me that it has been installed successfully. I need to export the certificate so that I can create public and private keys, but I can't find the certificate to do so.

  Firefox (Firefox Orange) > Options > Options > advanced > Certificates > authorities > export

• Too much security certificates, how to remove?

  Over the years working for different companies, I added specific security certificates. Apart from completely remove every trace of FireFox is a way I can just remove security certificates and start over?

  I like to keep my favorites and some addons. I don't remember which security CERT I needed and that I did not.

  Can I just delete them all and they ask to add as needed? I uninstall and reinstall?

  TY!

  There is usually no need to add exceptions for certificates unless you visit the website of the do not send all intermediate certificates or otherwise does not provide a string that accumulate certificate root.

  Always check why the site is not approved (see technical details) and if this is due to an intermediate certificate missing then see if you can install the intermediate certificate from another source.

  Some firewalls monitor secure connections (https) and send their own certificate instead of the certificate of the Web site.

  You can retrieve the certificate and check details such as WHO issued the certificates and the expiration dates of certificates.

  • Click on the link at the bottom of the error page: "I understand the risks".

  Let Firefox recover the certificate: "Add Exception"-> "get certificate".

  • Click on the "view..." button. "and inspect the certificate and the Coachman, who is the sender.

  You can see more details like the intermediate certificates that are used in the details pane.

• Firefox wrongly think that my site is using an invalid security certificate... clues?

  I recently installed a security certificate on my site.
  I tried different controllers of ssl and certificate seems fine.
  Firefox, however, don't like him and displays a warning page that says:

  www.Academi.pl uses an invalid security certificate.

  The certificate is not trusted because the issuer certificate is not approved.

  (Error code: sec_error_untrusted_issuer)

  This happens on Windows, Mac and Linux computers in my office.
  I also received a number of reports from users of the site who are experiencing the same problem.
  It seems that the problem does not occur in firefox 7.x, but I have to check properly.

  Anyone know a solution to this? I tried to remove the certificates manually in preferences, but it did not help.

  It worked for me! I had given up everything, but when I received this reply in my inbox this morning. I was skeptical at all first, think something so simple could not possibly solve all my problems... He did! Sometimes simple is best. Thank you all for the answers and help for this problem!

  2. scanned for the broswer addons > using Avast Antivirus I scanned for any Add - ons that may have been placed on my computer - found nothing.

  7 browsers uninstalled and reinstalled on the computer.
  8 restart the computer once the previous steps.

  I tried all the possible troubleshooting found on the Internet - if you can let me know if there is any more I can take - there seems to be a problem with my laptop because I have reset > I've never had this problem before.

  I found some details on this error notification ERR_CERT_DATE_INVALID
  The reason has been discussed in the Microsoft forum.

  It seems that Avast antivirus somehow involved in this error.
  Try disabling all the parameters that may affect the https sites.

  Of course, you can also try to uninstall Avast Antivir and could test other software like Avira Antivir.

• Why DigiCert always shows up on top of security certificates?

  I understand that Firefox now blocks all DigiCert security certificates. I use certificate patrol to monitor and compare certificates. Why am I still see some DigiCert certificates? (I keep Firefox updated)

  DigiCert has not violated - you're thinking of DigiNotar. They are two completely different companies.

  (DigiNotar is a small Dutch company, DigiCert is based in the United States and the largest provider of insurance high only certificates. http://en.wikipedia.org/wiki/DigiCert)

  This seems to be related to the 'Gamers unit' toolbar, using xml.freecause.com. Apparently freecause.com has left their security certificate expired, and those of us using the Snag bar receive this error because of the snag bar Gamers unite and not FireFox itself.

• Why, yesterday evening, I receive the message that the security certificate is not valid on the sites that I use all the time, as my account hotmail, facebook, paypal, etc.?

  I even got this message when I tried to post my question! It is said that Firefox can not verify a connection with mozilla, or any website, I am visiting, because the security certificate is not valid. It gives even the dates to which the certificate will be valid, and the date indicates that it is valid. So frustrating! I "replace" Firefox every time.

  The date / time set correctly in Windows Vista?

• Error message "security certificate is no longer available" while playing Backgammon

  Seems to me wrong to play backgammon online. I was not playig for awhile now, as it is said the security certificate is no longer available, but the last night I don't know what happened, I played, but tonight, he still says page not found after clicking "play". I had no problem before - why this view certificate rises. The address bar goes red when I type the address warning me that I should continue no longer.

  Hi whitebride,
   
  1. what Internet browser do you use?
  2. what operating system is installed on the computer? What is Windows XP/Vista/7?
  3. you play the built-in game or any other 3rd party or game MSN in the browser?

  I suggest you follow these steps and see if the problem is resolved.

  a. in Windows Internet Explorer 7, click on continue to this website (not recommended).
  b. a red address bar and a certificate warning appear.
  c. click the certificate error button to open the information window.
  d. click View certificates and then click on install Certificate.
  e. in the warning message that appears, click Yes to install the certificate.

  If the method above did not fix the issue, I suggest you try to perform an optimization of Internet Explorer on your computer and check the issue.
